To alZ 'whom tpmay concern.'

Be it known that I, CARL G. Jorma, a citizen of the United States, and a resident of Wilkinsbur in the county1 of p Allegheny 6 and State 0% Pennsylvania, ave invented a new and useful Improvement in Detachable Transformer Radiators, of which the following is a specification.

My invention relates to means for, and

10 methods of, applying detachable radiators to tanks in which an electrical device is tioned and in which an insulating flui -circulates about the electrical device and through the radiators for the purpose of cooling the apparatus.

Then the insulating fluid contained in a tank or reservoir becomes heated it tends to rise, and, by attaching to the tank or reservoir a radiator which has openings at the top and bottom, it is ssible to cause the fluid to pass through the) radiator from top to bottom and thereby become more effectively cooled than would be the case if the radiating surface of the tank alone were depended upon.

Therefore, it is the usual custom to supply all transformer tanks, in which apparatus of the oilinsulated type is to be positioned, with one or more radiators having a comparatively large radiating surface. Radia tors of the character designated occupy a great deal of space in a transverse direction and, therefore, limit to a great degree the size of tank which may be shipped with *5 the radiators in place. Therefore, when the tanks reach such size that the addition of the radiators thereto for shipping purposes would bring the total volume of the apparatus beyond the limits imposed by car slzes,

L0 bridge clearances and other shipping considerations, it is necessary to ship the radiators separately.

It is obvious that such separate shipping of the tank and its radiators precludes the 5 poibility of the tank and radiators being filled with the insulating Huid before shipment. This is a distinct inconvenience, since the fluid must be shipped separately and, in transformer tanks o lar sizes, and such 0 separate shipment of the uid requires considerable containing s ace.

An alternative met od of shi ping requires the filling of the tank 'wit insulating Huid after caps have been placed over 5 the openings to which the transformer radiators are to be attached. By this method, approximately three-fourths of the insulating fluid may be shipped in the tank and' the remainder be placed in barrels and shipped separately. However, when the point of installation is reached, it is obvious that, to attach the radiators to the transformer tank, it is necessary that all of the fluid contained therein be drained. This entails considerable ex use since containing means to hold the dui l,which normally lille the transformer tank must be of considerable size, and, moreover, means must be provided-for draining the'tank, placing the radiators in position and thereafter re lacing the insulating fluid in the tank from t e top, unless some more or less ex nsive method, such as siphoning, etc., be opted.

If, at any time during the o ration of the transformer, one or more o the radiators become faulty, that is, develops a leak, clogs, or otherwise, it is necessary to drain the entire apparatus before even one of the radiator structures may be detached and repaired. It is obvious that such considerations as given above limit, to a great extent, the flexibility of repair of transformingiapparatus of the character described.

oreover, it is very desirable to ship the transformer with the insulating duid .in place since' there otherwise is great danger of the windings becoming saturated with moisture and subsequently developing serious faults.

One object of my invention is, therefore, to provide means whereby the transforming paratus may be placed in its tank and ipped surrounded by oil, and, for this u ose, I provide novel closure means for `closmgnhe openings to which the radiators are to attached.

When the int of installation is reached, mv improv means of attachment further mit of the attachment of the radiators to the tank, the withdrawal of the closure means, and the subsequent lli of the radiators with the insulating fluid 1n the manner desired for operating conditions.

Again, my detaching means admit of the `detachment of any radiator in which a fault ma develop, even though the same be filled wt fluid, that is, they provide means whereb any one radiator may be detached from t e tank, and at the same time, the openings from which the radiator is separated may be closed in the same manner that they were closed during the initial shipment of the tank filled with insulatin fluid.

Other obvious advantages of my etaching means and the method of operating the same in connection with transformer radiators will appear to those skilled in the art, in the following description of the structure and the o ration thereof.

For a tter understanding of my invention, reference may be had to the accompanying drawing in which:

Fig. 1 is a sectional elevational view of a transformer and a containing tank filled with insulating fluid and having auxiliary cooling means, such as radiators, attached thereto; Fig. 2 is a detail sectional view of the top header of one of the radiators embodying my detachin and attaching means, the operating means geing shown in two extreme positions; F ig. 3 is a detail sectional view taken on line III-III of Fig. 4 and illustrating in detail, the engagingportion of my closure operating means; ig. 4 is a sectional view of the structure shown in Fig. 3 and taken on the line IV-IV thereof; and Fig. 5 is a sectional View showing an alternative form of closure means and operating means. Y

Referring more particularly to Fig. 1, a tank 1 containing an electrical device 2 and filled with fluid for insulating and cooling said electrical device, is shown. To the right of the tank 1 is shown a radiator member 3 of usual construction, with the exception of a novel form of headers 4 and 5. It will be observed that the radiator 3 is shown as filled with insulating fluid; that is, it is in communication with the main tank 1.

At the left-hand side of the tank 1 is shown a radiator 6 but, in this latter case, the radiator is not filled `with insulating Huid because the tank 1, while being mechanically connected with the radiator 6, is still closed by closure means 7 which are seated within the o nings 8 registering with similar openings 1n the radiator structure.

The top header 4 of either of the radiators 3 and 6 is shown in detail in Fig. 2. A wall. portion 9 of the tank l is shown as provided with the opening 8, the metal around this opening being flanged at 10 and provided with interior screw threads for the pur ose of receiving a threaded member 11. he threaded member 11 comprises a closure member for the opening 8 and, when engaging properly, the screw thread with which the opening is provided forms a Huidti ht closure for the tank 1.

gIhe header 4 is likewise provided with a flanged member 12 which is ada ted to so engage the tank-wall flanged mem r 10 that registry i's established between the openings in the tank and in the radiator. The flanged portion 13 of the header 4 provides a path 1,400, isa

for the fluid to enter the radiating ipes of the radiator. At the o posite emfof the header member 4 from t e dan d member 12, threads are provided upon w ich a pipecap member 14 or an auxilia perforated cap member 14a may be secure and it will be observed that, by the positioning of the member 14, the header 4 is closed and made fluid-tight. It will be understood that all of the radiators are provided with the cap members 14, which are used at all times other than those during which the radiators are being attached to, and detached from, the tank; while the special cap member 14a, which is illustrated in Fig. 2, is used in con'unction with an auxiliary member 15 an a acking 16 for purposes to be hereinafter escribed.

It will be observed that both the cap member 14a and the auxiliary member 15 are apertured to permit the passage therethrough of a closure-operating means 17, comprising an engaging socket member 18, a longitudinally extending connectin rod 19 and a detachable operating hand e 20, the handle 20 being made detachable in order that it may be removed from the members 18 and 19, whereby the closure operating means may be disengaged from the members 14a, 15 and 16. The interior portion of the header 4.

vwhich is adjacent to the opening over which the cap members 14 and 14a are placed, is threaded at 21 to receive the member 11.

The view shown in the full lines in this figure represents the condition obtaining in the transformer structure after the radiator member has been attached by means of the flanged members 10 and 12 to the tank, the tank 1 being filled with fluid, and after the closure-operating means 17 has been passed throu h the radiator header and has enga the closure means 11, the operation of all of which will be described more in detail hereinafter. The broken lines, on the other hand, represent the positions of the various elements after the closure means 11 has been unscrewed, withdrawn to the opposite end of the radiator header 4 and there secured, the closure-operating means 17 having not as yet been withdrawn entirely from the associated structure of the radiator header.

Fi 3 and 4 will be considered to ther as showing the detailed structure o what I now consider the preferred form of the engaging member 18 of the closure-operating means 17. It is desirable that the member 18 shall be of such size and shape that it 'may pass through a pipe having a diameter no greater than its own diameter and, while within said pipe, may enga the protruding portion of a member whic it is desired to withdraw inst pressure. It is obvious, therefore, t at means must be provided, in conjunction with the member 18, which will admit of its passage through a pipe having a diameter no greater than its own and, at the same time, allow it to pass over and engage a protruding member having a diameter commensurate with the diameter of socket existing in the member 18. To attain this end. I have provided the member 18 with resilient grip ing means 22 which, in the form of devlce siiown in Figs. 3 and 4, are actuated by spring members 223-23.

In Fig. 5 I have shown an alternative construction of the closure means which may be used, and have also shown closure-operating means adapted to co-act theiewith4 to position, in the desired manner, a closure means of this type.

Having described a transformer and radiator tank connected in accordance with my invention, the manner of attaching the radiator member t'o, and detaching it from, the main tank will now be described.

Assume that the main transformer tank 1, containing the electrical device 2 and filled with the maximum quantit of insulating fluid, has been shipped to t e point of installation se arately from the re uired number of ra iator elements. oreover, it should be remembered that, in order to so convey the tank 1 filled with oil, it has been necessary to close each of the openings, which are adapted to re ter with the radintor openings, by the c osure means 11.

The radiator element 8 is attached to the tank 1 by means of flanges 10 and 12 in a well known manner. For purposes of convenience, the cap member 14 is usually in osition when the radiators are shippe and) this member, therefore is first removed. The auxiliary pipe cap 14a, as well as the packing members 15 and 16, are usually in place on the closure operating means 17, since only under s ecial circumstances is it necessary to with raw the rod 19 through the apertures in the members 14a, 15 and 16 by removing detachable handle 20. In other Words, the entire operating mechanism which is used for removing the closure means mav be readily carried from place to place an used in an integral form.

The standard cap piece 14 having been removed, the entire c'osure-operating mechanism is brought to juxtaposition with the header 4, the gripping member 18 is passed through the header, and. inall ',the auxiliary cap piece 14a, is Screwed tight y into position upon the open end of the header, this last operation insuring the existence of a fluidtight closure for the top header of the rndiator. The engaging portion 18 is now pushed forward until the socket portion thereof engages the protruding ortion of the member 11, as far as the resi ient gripping means 22. A sharp blow will now drive the member 18 completely over the protruding portion of the member 1l, and the resilient means will be seated in the rccesses provided for this purpose in the pro.

trading portion of the member 11. The socket of the member 18 and the coacting protruding portion of the member 11 being poly onzil in form, rotation of the handle mem er 20 will result in the member 11 being disengaged from the threaded portion of the opening 8 and immediately, the fluid which fills the tank 1 will flow into the header 4 and the remainder of the radiator structure 3. Therefore, the closure member 11 must be withdrawn from the opening 8 against fluid pressure. The member 17, which is now engaging the closure means 11, is drawn through the aperture in the cap 14 until the threads of the member 11 engage those at 21. By rotation of the member 17, the closure member 11 is then firmly secured at 21 to preclude the flow of fluid through the o enmg over which the member 14 is place Since the next step in the operation 1s to unscrew the member 14a and since the closure means 11 and the operating means 17 are now in the osition indicated by the dotted lines, it wilibe a simple mutter to disengage the member 18 from the protruding portion of the closure means 11. The auxiliary cap member 14a. and the associated closure operating means is then rem'oved and thepermanent solid cap member 14 placed in p`oS1t11on, as shown at the right-hand side of From the foregoing, it is obvious that I have provided means whereby the closure means 11 are withdrawn and, after fluid communication is established between the radintor and main transformer tank, are thereafter employed to close the opening at the right-hand end ofV the header of a radiator member. Since the closure-operating means 17 is applicable to the closure members in all of the openings, this device may be used to attach all of the radiators to the transformer tank, in the manner hereinbefore described in connection with the header illustrated.

As further set forth. my radiator-detaching means are also employed to detach any radiator in which a fault muy develop from the transformer tank and, at the sume time, allow the latter to operate under normal conditions. To do this without draining any of the fluid with which the tank and the associated radiators ure filled, the following operation is pursued.

The fluid communication between the main tank and either the top or bottom of the radiator may be interrupted, if desired. and. for purposes of convenience, l will illustrate such interruption as being performed in the top header of the radiator illustrated in Fig. 2.

The pipe-cap member 14 is first removed and a fluid tight closure is still present on account of the member 11 being seated in the threads 21. The engaging portion 18 of the device 17 is then pressed over the protruding ortion of the closure means 11 which, w en the radiator is filled with oil and operating under normal conditions, is secured in the threads at the right-hand end of the header, as shown. The member 14a and the packing-gland sections 15 and 16 are then screwed into place, whereby a fluidtight cap is placed over the opening at the right-hand of the header. By rotation of the handle 20, the member 11 is now unscrewed from the threads at 21, pushed through the header and screwed into position in the opening 8. In like manner, the bottom header of the particular radiator which is being detached is separated from fluid communication with the tank.

At this point in the detaehing operation, the radiator has no fluid communication with the main tank, although it is mechanically attached thereto. The drains in the bottom of the radiator may now be opened and thesmall quantity of oil contained in the radiator be withdrawn. It is apparent, therefore, that I have been able .to detach an affected radiator from the tank for purposes of repair without having the radiator or the tank in any way supplied with gate valves or other expensive auxiliary apparatus. The association of valves and other projecting attaching apparatus is especially nndersirable it it is desired to ship a transformer tank filled with oil a long distance, for the reason that such valves will be easily broken ofi1 in transit or bent in such way that they will not register correctly with the radiators intended for the tank.

The foregoing description has been directed principally to fluid-containing vessels in which electrical devices are positioned and to which auxiliary liuidcontaining vessels, such as radiators. are attached. It is obvious, however, that my invention is broad enough to cover the attachment and detachment of any two fluid-containing vessels. wherein it is desired to attach or detach one vessel to or from another while the one or the other is filled, or while both vessels are filled with liquid. Such flexibility of attachment and detachment may prove especially desirable when it is necessary to ship a large vessel filled with fluid and thereafter attach it to another vessel without emptying, and when this operation must be performed without the interposition of valves, etc.

lVhile I have described one embodiment of my invention, it is obvious that other detaching and attaching means may occur to those skilled in the art to be used in a manner analagous to those above described and. therefore, I desire that my invention be construed as broadly as is permitted by the prior art. Moreover, I believe that the device with which I operate the closure means is novel in its arrangement of the resilient engaging members, and I desire this device also to be construed as broadly as possible.
